From Hitler’s American Model which documents how Nazis were inspired by American race law to effect their racial purification policies:

Nazi law was different, Hanke declares, because the German laws of the early 1930s were “but one step on the stair to the gas chambers.” Unlike American segregation laws, which simply applied the principle of “separate but equal,” German laws were part of a program of extermination. Now part of the problem with this argument, which Hanke is by no means alone in offering, is that its historical premise is false: It is simply not the case that the drafters of the Nuremberg laws were already aiming at the annihilation of the Jews in 1935. The concern of early Nazi policy was to drive the Jewish population into exile, or at the very least to marginalize it within the borders of the Reich, and there were serious conflicts among Nazi policy makers about how to achieve even that goal.
